nota del editor : esta publicación destaca los datos de Webb Science in Progress, que aún no ha pasado a través del proceso de revisión de pares.
Investigadores identificó una galaxia con lente previamente desconocida por primera vez en la primera vez de la nueva hora de la Galaxia de la Galaxia de la Nasa. izquierda. Un débil arco rojo aparece en el recuadro a las 10 en punto. Esta es una galaxia muy lejana cuya apariencia está deformada a la imagen de Webb. Su luz está doblada por la gravedad de la galaxia elíptica de primer plano. Además, su apariencia está duplicada. El arco rojo estirado reaparece, como un punto, a las 4 en punto.
Estas imágenes de la galaxia con lente son tan débiles y tan rojas que no fueron reconocidas en los datos de los Hubble, pero son inconfundibles en la imagen de infrarrojo cercano de Webb. Simulaciones de galaxias con lentes gravitacionales como esta ayudan a los investigadores a reconstruir cuánta masa hay en estrellas individuales, junto con cuánta materia oscura hay en el núcleo de esta galaxia.
Esta imagen incluye datos ultravioleta y visibles del telescopio espacial Hubble de la NASA.
Webb se construyó un equipo en la universidad de ARIZONA de ARIZON. Martin’s Advanced Technology Center.

| About The Data | |
| Data Description | This image was created from JWST and HST data from proposals: (R. A. Windhorst), (B. W. Holwerda) ; (B. W. Holwerda) |
| Instrument | HST>WFC3/UVIS JWST>NIRCam |
| Exposure Dates | 19 June 2015, 16 Dec 2018, 2 July 2022 |
| Filters | HST> F336W, F606W JWST> F356W, F150W, F090W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope and the Hubble Space Telescope using the NIRCam and WFC3/UVIS instruments respectively. Several filters were used to sample infrared, visible and ultraviolet wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Red: F356W Yellow: F150W, Green: F090W, Blue: F336W + F606W |
| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
| About The Data | |
| Data Description |
|
| Instrument | The science instrument used to produce the data. |
| Exposure Dates | The date(s) that the telescope made its observations and the total exposure time. |
| Filters | The camera filters that were used in the science observations. |
| About The Image | |
| Image Credit | The primary individuals and institutions responsible for the content. |
| Publication Date | The date and time the release content became public. |
| Color Info | A brief description of the methods used to convert telescope data into the color image being presented. |
